Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-90ahistwx' to each side of the equation.
-90ahistwx + 6x = 90ahistwx + -90ahistwx

Combine like terms: 90ahistwx + -90ahistwx = 0
-90ahistwx + 6x = 0

Factor out the Greatest Common Factor (GCF), '6x'.
6x(-15ahistw + 1) = 0

Ignore the factor 6.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-15ahistw + 1)' equal to zero and attempt to solve: Simplifying -15ahistw + 1 = 0 Reorder the terms: 1 + -15ahistw = 0 Solving 1 + -15ahistw = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -15ahistw = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -15ahistw = 0 + -1 -15ahistw = 0 + -1 Combine like terms: 0 + -1 = -1 -15ahistw = -1 Add '15ahistw' to each side of the equation. -15ahistw + 15ahistw = -1 + 15ahistw Combine like terms: -15ahistw + 15ahistw = 0 0 = -1 + 15ahistw Simplifying 0 = -1 + 15ahistw The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
